Battery storage, explained

What it is

A home battery stores electricity to use later. With solar, it stores your surplus generation for the evening or a power cut.

No solar? A battery can still charge from the grid on a cheaper off-peak tariff and run your home at peak times.

We add batteries to new and existing solar systems, and to homes without solar, across Ivybridge, Plymouth and the South Hams.

Who it suits

  • Homes with solar that export a lot in the day
  • Households on (or happy to switch to) a time-of-use tariff
  • Homes that want backup in a power cut
  • Anyone planning solar later

Why it’s worth it

The benefits

Use more of your solar

Keep daytime surplus for the evening instead of exporting it.

Cheaper off-peak power

Charge when electricity is cheaper and use it at peak times, depending on your tariff.

Backup options

Some systems can keep key circuits running in a power cut.

Smart control

Monitor and manage it from an app.

Things to consider

  • How much you benefit depends on your usage, tariff and whether you have solar.
  • The battery needs a suitable location, which we check against current safety guidance.
  • Backup power isn’t automatic on every system; we’ll explain the options.

Payback

How quickly does a battery pay back?

On its own, a battery’s return on investment is typically closer to two to six years, depending on how you use electricity and your tariff.

  • No scaffolding
  • No roof survey
  • Nobody clambering on your roof
  • Usually fitted in a day or two, with very little disruption

What’s included

What a typical install includes

Survey and sizing

We look at your usage, tariff and any existing solar to size the battery properly.

Battery and inverter

A battery plus a hybrid or battery inverter, installed in a suitable location.

Backup (optional)

Wiring for backup of key circuits if you want it and the system supports it.

Setup and handover

App setup, tariff settings, testing, certificates and DNO notification.

Grid connections

Grid connections and paperwork, all handled

We have a strong working relationship with National Grid in the South West. We work with them to confirm how much your site can export and what size of solar, battery and inverter is approved for your property, whether that’s a home, business, industrial unit or farm. Every installation follows MCS, NICEIC and BS 7671 regulations. We handle the full process for you: National Grid applications, MCS registration, NICEIC certification, and your certificates and warranty documents at handover.

The technical bit: smaller systems are usually notified to the network operator after install (G98). Larger systems, which includes most commercial, industrial and farm systems, need approval before install (G99), and the network operator can set an export limit.

Rules & regulations

In plain English

A simple overview to help you plan. We check the details for your property at survey.

Where a battery can go

Current guidance (PAS 63100) sets out where home batteries can safely be installed, for example keeping them out of escape routes. We follow it when choosing the location.

Building Regulations and electrical safety

The electrical side is designed and certified to BS 7671 (the UK wiring regulations) and notified under Part P by our NICEIC-registered team. You get your certificates at the end.

FAQs

Common questions

Can I have a battery without solar?

Yes, absolutely! A battery can charge on a cheaper off-peak tariff and run your home at peak times, and we’ll tell you honestly if it suits your usage.

Will it keep my power on in a power cut?

Yes, it can, as long as the system is set up for backup! Not every system does this as standard, so we’ll explain your options and can wire in backup for key circuits if you want it.

How big a battery do I need?

We’ll do the maths for you! It depends on how much electricity you use in the evening and overnight, plus your solar if you have it, so we size it properly at survey.

Is it worth it?

Yes, for many homes it is. A battery on its own typically pays back in closer to two to six years, depending on your usage and tariff, and we’ll go through the figures for your home.
